--- Comment #5 from Fabian Maurer dark.shadow4@web.de --- Created attachment 62962 --> https://bugs.winehq.org/attachment.cgi?id=62962 Glitch in the demo
The game has a demo which can be used to reproduce the issue. Links to demo: http://frontwing.jp/product/grisaia/download.html
A direct link: http://suezou.dyndns.org/dl2010/frontwing/gurizaia/Grisaia_trial_web.zip (700MB and might take a while to download)
Guide to test: 0) Get the demo 1) Click through the installation. It installs to "C:\frontwing\SomeJapaneseFolder" 2) run wine "Grisaia", it opens a dialog where you should click the right option (windowed mode) 3) in the main menu click the first option, and then any of the scenes you can select. 4) Press left-ctrl to fast-forward or the mouse to advance one by one 5) Screen tearing is pretty obvious (see attachment)
I assume it might be related to the driver, so it would be great if someone could test! Using AMD R9 285 and mesa on ArchLinux x64.
